httpd多虚拟主机的实现

基于ip的多虚拟主机

在同一台服务器上配置多个ip

[httpd_server]# ip address add 192.168.43.100/24 dev ens33
[httpd_server]# ip address add 192.168.43.101/24 dev ens33
[httpd_server]# ip address add 192.168.43.102/24 dev ens33

建立多个站点

[httpd_server]# mkdir /data/{a,b,c}site -pv
[httpd_server]# echo /data/asite/a > /data/asite/index.html
[httpd_server]# echo /data/bsite/b > /data/bsite/index.html
[httpd_server]# echo /data/csite/c > /data/csite/index.html

配置文件

[httpd_server]# vim /etc/httpd/conf.d/a.conf
<virtualhost 192.168.43.100:80>
	documentroot "/data/asite"
	<directory "/data/asite">
		require all granted
	</directory>
</virtualhost>

[httpd_server]# vim /etc/httpd/conf.d/b.conf
<virtualhost 192.168.43.101:80>
  documentroot "/data/bsite"
  <directory "/data/bsite">                                                                                     
    require all granted
  </directory>
</virtualhost>

[httpd_server]# vim /etc/httpd/conf.d/c.conf
<virtualhost 192.168.43.102:80>
  documentroot "/data/csite"
  <directory "/data/csite">                                                                                     
    require all granted
  </directory>
</virtualhost>

启动服务

[httpd_server]# httpd -t
[httpd_server]# systemctl start httpd

客户端访问

[client]# curl 192.168.43.100
/data/asite/a
[client]# curl 192.168.43.101
/data/bsite/b
[client]# curl 192.168.43.102
/data/csite/c

基于 port 的多虚拟主机

配置文件

[httpd_server]# vim /etc/httpd/conf.d/a.conf
listen 81                                                                                                       
<virtualhost *:81>
  documentroot "/data/asite"
  <directory "/data/asite">
    require all granted
  </directory>
</virtualhost>

[httpd_server]# vim /etc/httpd/conf.d/b.conf
listen 82
<virtualhost *:82>                                                                                              
  documentroot "/data/bsite"
  <directory "/data/bsite">
    require all granted
  </directory>
</virtualhost>

[httpd_server]# vim /etc/httpd/conf.d/c.conf
listen 83
<virtualhost *:83>                                                                                              
  documentroot "/data/csite"
  <directory "/data/csite">
    require all granted
  </directory>
</virtualhost>

客户端访问

[client]# curl 192.168.43.17:81
/data/asite/a
[client]# curl 192.168.43.17:82
/data/bsite/b
[client]# curl 192.168.43.17:83
/data/csite/c

基于主机头的虚拟主机

配置文件

[httpd_server]# vim /etc/httpd/conf.d/a.conf
<virtualhost *:80>
  documentroot "/data/asite"
  servername www.a.com                                                                                          
  <directory "/data/asite">
    require all granted
  </directory>
</virtualhost>

[httpd_server]# vim /etc/httpd/conf.d/b.conf
<virtualhost *:80>                                                                                              
  documentroot "/data/bsite"
  servername www.b.com
  <directory "/data/bsite">
    require all granted
  </directory>
</virtualhost>

[httpd_server]# vim /etc/httpd/conf.d/c.conf
<virtualhost *:80>
  documentroot "/data/csite"
  servername www.c.com                                                                                          
  <directory "/data/csite">
    require all granted
  </directory>
</virtualhost>

客户端访问
客户端访问服务器的域名，需要dns服务器，由于没有配置dns服务器，所以在客户端这边配置hosts文件

[client]# vim /etc/hosts
192.168.43.17 www.a.com www.b.com www.c.com

[client]# curl www.a.com
/data/asite/a
[client]# curl www.b.com
/data/bsite/b
[client]# curl www.c.com
/data/csite/c

telnet 模拟浏览器访问httpd服务器

[client]# telnet www.a.com 80
